Appiicauon mea November iaiez. semi No. 674,407.

To all whom t may concem that I, DONALD DAMON ORMSBY, a citizenof the United States, and a resident of Syracuse, county of Onondaga, and State of New York, have invented certain new and useful Improvements in Differential Carriers, of which the following is a full, clear, concise, and exact description, such. as will enable othersskilled inthe art to which the invention relates tomake and use the same, reference being made therein to the accompanying drawings, which form apart of this specification.

This invention relates to means for locking in adjusted position members such as the adjusting sleeves of drive pinions, and is illustrated as embodied in the differential A carrier member with a cross-bore, shown as carrierof an automobile. An object of the invention is to providea simple construction which will avoid the necessity of splittingthe carrier to secure a clamping action for holdingthe adjusting sleeve in Vany desired position.` j Having this object 1n`view,'thc invention contemplates" providing the usual `tubular substantially tangent :tol` its inner surface, in which there is arranged `means for engaging-and'clamping in adjusted position 4the usual sleeve used for the purpose of adjust ing' the position ofthe drive Vpinion which engages Athe ring gear "of the differential. Inv one desirable construction, there lare a pair of drawV plugs arranged in ithis bore which VIare drawn toward fone another inanipulatingfa bolt passin'gthrough them so as' to'clampthem firmly against the ei;- teriorA of Vthepin'ion` adjusting sleeve.

Preferably, a key is provided, which may be held `bytheabovedescribed clampor its equivalent, whic'hengages the sleeve fand an internal ring, lwhich may be theusual ring holding the antilfriction bearing in place inside of the sleeve, in ordertoprevent pos- .Sib'le relative movement which would loosen the partsand' allow playin 'the antifriction bearing. In the arrangement'shownin the drawings,'the key engages lugs formed on the sleeveand'the internal ring, and,'if' desired, also lugs on an external'locking ring,

ciampiV L The above and other objects'iand features ofthe invention; including various novel :if

combinationsof parts anddesirable particular constructions, will be apparent from the followingdescription of one illustrative embodiment shown inthe accompanying drawings, invvhich` f y Fig. lisa topplan view,vpartly 4broken awayjshowing'part of a banjo type rear axle' W f 'i "F 2is a view showing'part of Fig." u1' on a larger "scale but additionally broken away to show certain parts in horizontal section; and F ig. 3 is a seotionfon the line 3 3` ofi-Fig. 2 showing the relation ofthe above descibed locking key to theother parts. i

In the embodiment selected for illustra# tion, theinventionl is'shown'asfapplied in a rear laxle* construction including the usual banjo type housing "10 'in `which are arranged Athe 'live axles 12 and" '14e connected inthe usual manner `by' a differential supported by a differential Vcarrierl bolted to the housing `l0.` `VVhileshow'nin a banjo 'typefaxlathese parts maybeof anydesire'd construction. IThe stub shaft 18, `driven in the -usual manner from the propeller shaft, is substantially coaxial 1vwith respect to the tubular 4Vcarrier member 16 and is supported bya pair of 'anti-friction bearings, the forward yone'of which Disshown at T20. *The rear antilfriction bearing is arranged in'tlie `usual manner'infengagenient with the drive pinion on th'eiend of the shaft 18,-- which isin mesh iwith they ring gear of the fdif. .ferentiaL thei rear antifriction bearingbe ing slidably'jarranged in an internalflange in 'the tubular housing 16. andy held inplac'e bya spacing sleeve 22; vThe ishaft-andts bearings are arrangedto be adjusted axially ofthe sh'a'fttoprovide :the properfmeshbe- L tween the pinion and' theringgar by turning an adjusting sleeve or bushing 24thread`- ed into `thetuloulartcarrier` member V16 at 26," the sleeve 24 being `provided- 'with an internal flange- 28rv which supports f the antifriction bearing 20. f The anti-friction bear-- iiigisheld against-Athelange V28 by a ring 30 threaded 4into the sleeve and `which f is;` pref erably 1` arranged to' oomprss "a packing 32.

A11 of @heerenwegen para afs/'illus split, it

trated as being of substantially the usual construction, except as further described below, and extended description thereof is therefore considered unnecessary.

Heretofore it has been consideredf'necessary to split the tubular carrier member 16 in order to,utiliz,e a binding or clamping screw 'totigntenj't 'upon the Sleeveffzeto hold itin adjusted position. Vhenthis is done, after the tubular memberhl6 -is bored out to provide an accurate internal surface, there is great diliiculty in avoiding distor-y tion in providing the clamping slot and in tightening fupthej clamping' screw. v'Accrding -to the present invention; such possible distortion"is'avoided' by leaving the` end-of tlie tubularcarrier member 16 solid and pro# vidin-g a' cross-bore 34 substantially I tangential With respectto "the inner surface'of 'the member 16 and formed in anenlargement near the end ofthe' latter, in which maybe arranged means'lengagggingr they Isleeve 24 for clamping it in adjusted position Without'the possibility lof'=any distortion lof' the lvarius parts. 'Since the carrier member '-16 is `not has: continuous :peripheral `engagement with the sleeve 24 at both sides ofthe crossboie. In the particular arrangement 'slidvvn'inA the drawings, there is la'` perforated draw plug 36"and"acooperating 'd'rawfplug 38k Whiclr'is tapped -torecei'ven clamp-bolt 40"Wliich can 4fbe tightened' `to idraw" theK4 plugs 36 and" 38 irinlyagainstthe" exterior Vof the clamping surfaces curved onarcs-having the sa me vradiusf'as` the' exterior surface of the sleve and theflinteriorisurfae "of the carrier member. lfreferably,Y ther sleeve 24' and the ring-'SO' are provided withV lugs 42,"and, -if desired, a locking-ring 4:4 tvthreaded 'onl the outside' 4'of' the 'sleeve' 24in 'eugagement with tlie end vof'the ""tubular member 116may be provided With radially extending lugsv '44', all ofi 'the' 'lugs beirrg'soarranged` thatV when the. parts are'finea'ny' desi-red' adjusted -positidn, i particular ones of the lugs may be 'brought into alignment 'with each other. The lugs' are engaged, -tof #hold the parts7 in suchvfdj ustedi positions, 'by 'l a "key 46 'hav ing f a' pair of radially arranged open-'ings seating 4over ilags-'42 and nav'ngafsten portion' 48: engaging betWeen'ladj-acent lugs 44.1, which' key 'mayconve'nientlyf be held-in place b 'y having 'a perforated 1vhead "50 fthro'ugh Whidnpasses the" clampingboltlt). If" desired,` suitable @spring lock 'Washers 52 'may beprovided.

It `Will be seen that' the *various p-artsy Imay be readily"-adjusted,'a'nd vvhen'so' adjusted are' A'firmly held' iin p'ositiorfbyA tighteningthe vbolt 140, While 'at the'fsme'time it -is' unnecessary' -to providej any slot' 'in the tubular 'memberl6, so that there-'isfno possibility of distortion" of-this f-part f ei-t'her'in forming' the 'sie aan agree-inea@Campagnes,
